New player progress hack or old one with player not rolled back?

Just logged a “bug” after having seen the following profile while looking at the people on same server.
This player is level 2 999 which, from his profile, he reached in 23 hours with ultimately few achievements…

did they get rolled back ? also seen one of those few days ago in some speedtrap ranking, a cheater is a cheater no matter if new or old they should get banned no more no less
abusing an exploit that harsh is no difference for me to any other kind of cheater/hacker

I am not for maximum punishment without a minimum kind of trial + I think having all their profile reset to zero along with fixing the game is much more interesting for the community and punishment for them
